tmpCnv() CATALOG
tmpCnv( expression1_ ¡tempUnit1 , _ ¡tempUnit2 )
⇒ ⇒ ⇒ ⇒ expression _ ¡tempUnit2
Converts a temperature value specified by
expression1 from one unit to another. Valid
temperature units are:
_ ¡C Celsius
_ ¡F Fahrenheit
_ ¡K Kelvin
_ ¡R Rankine
For example, 100_ ¡C converts to 212_¡F:
To convert a temperature range, use @ @ @ @tmpCnv()
instead.
tmpCnv(100_¡c,_¡f) ¸ 212.ø_¡F
tmpCnv(32_¡f,_¡c) ¸ 0.ø_¡C
tmpCnv(0_¡c,_¡k) ¸ 273.15ø_¡K
tmpCnv(0_¡f,_¡r) ¸ 459.67ø_¡R

@ @ @ @tmpCnv( expression1_ ¡tempUnit1 , _ ¡tempUnit2 )
⇒ ⇒ ⇒ ⇒ expression _ ¡tempUnit2
Converts a temperature range (the difference
between two temperature values) specified by
expression1 from one unit to another. Valid
temperature units are:
_ ¡C Celsius
_ ¡F Fahrenheit
_ ¡K Kelvin
_ ¡R Rankine
1_ ¡C and 1_¡K have the same magnitude, as do
1_ ¡F and 1_¡R. However, 1_¡C is 9/5 as large as
1_ ¡F.
To get @ , you can press ¥ c ¤ [ D]
(or 2 ¿ 1 5 ).

For example, a 100_ ¡C range (from 0_¡C to
100_ ¡C) is equivalent to a 180_¡F range:
